remap callback argument error on Ruby

[hadamak]

How to use the remap callback on Ruby?

# script:  ruby

def remap(t,x,y)
	t
end

def TIC
	cls 13
	map 0,0,30,17,0,0,-1,1,remap
end

'remap': wrong number of arguments (0
or 3) (ArgumentError)
user code:3:in remap
user code:9:in TIC
user code:7

Some detective work: the message "wrong number of arguments (X for Y)" was changed in mruby 3 years ago: mruby/mruby@c4bca7c

Another commit from around the same time which could be relevant: mruby/mruby@16e3888

Maybe mruby just needs an update, here.
